Austal wins Istanbul ferry order
Austal has signed a contract for two 88 m high speed vehicle-passenger catamarans for the Istanbul Metropolitan Municipality. This follows submission of a fully compliant proposal with the lowest price offer in an international tender that began earlier this year.
To be operated by Istanbul Deniz Otobusleri (IDO) the identical new ferries are scheduled for delivery in 2007 and have a capacity to carry 1,200 passengers and 225 cars or 126 lane meterss of trucks plus 158 cars.
The new Austal ferries are designated to operate on a 39 nautical mile reciprocal service across the Marmara Sea between Yenikapi (Istanbul) and a new port development in Mudanya servicing the city of Bursa.
Each ferry will be powered by four MTU 20 cylinder 8000 series diesel engines driving a Lips propulsion system through four Reintjes gearboxes.
Austal Sales Manager, Chris Pemberton said this combination was specifically developed to achieve the performance targets with 1,200 passengers and 225 cars onboard.
"When faced with challenging performance requirements set out in the tender document our design team analyzed many different propulsion configurations to finally attain the optimum result," he said.
The vessels have a maximum deadweight of 470 tonnes and are designed to operate with this load at speeds in excess of 36 knots at 90% of maximum engine power.
The vehicle deck offers a clear height of 4.0 m under the raised mezzanine decks, which are being installed for the first time on a Turkish fast ferry enabling greater flexibility in seasonal load handling.
Passenger accommodations will be located on two decks,
The bridge deck will accommodate 278 Business Class passengers. The Tourist Class upper deck for 922 passengers will also providing catering and shopping facilities and a children's recreational area. .
Passenger loading is enhanced by specialised boarding ramps and entrances that enable safe, simultaneous movement of vehicle and passenger traffic. The main engines exhaust via dry stacks to keep fumes away from passengers during boarding and departure.
The vessel is being built in accordance with the requirements and under the survey of Germanisher Lloyd, conforming to International Maritime Organisation codes and Turkish Flag and Port State Regulations.
IDO is Austal's largest commercial customer. Austal has previously supplied it with eight vessels.
